Application filed August 27, 1889- Serial No. 322,112. (No model.)

To aZZ whom it may concern: D and D are the clamps, the best because Be it known that I, AXEL A. STROM, a citithe strongest form of which is that shown, zen of the United States, residing at Austin, since it involves a metal bar bent edgewise in the county of Cook and State of Illinois, upon itself near its extremities, to afford the 5 have invented a new and useful Improvement hook-shaped ends 7', which conform to the up in Railway-Frogs, of which the following is a per surfaces of the outer flanges and sides of specification. the webs of the Wing-rails.

The object of my invention is to provide To secure the parts of the frog togetheigthe simple and thoroughly practical and effective clamps D and D are adjusted, respectively, IO means for securing the parts of a railwaynear the wider and narrower extremities frog together, and'which shall admit of ready thereof, to extend across its base and over the readjustment to effect tightening of such outer flanges of the wing-rails, when they are parts whenever they become loose in the use wedged into their positions of firmly securing of the frog. To these ends I employ, as it is the parts together by driving them toward 15 common to do, to embrace the frog near its the wider end of the frog, whereby the latter respective flaring and tapering ends, clamps serves as the sole means of tightening the which extend across the base and over the clamps upon it, and, as a consequence, securouter flanges of the wing-rails, and to efiect ing its parts together thus Without the emseouring and tightening of the parts together ployment of wedge or keys and blocks, or 2c in their initial adjustment, and whenever both, between the hooked ends of the clamps they become loose with the wear of the frog and the adjacent surfaces of the wing-rails. in operative position, I utilize the wedge af- Should the parts of the frog, in the use of forded by the lateral edges of the frog itself the latter, become loose, they may be readily by driving the clamps toward the flaring exand effectually tightened by driving the 2 5 tremity, thus accomplishing the purpose withclamps still farther toward the widening end out the use of the common keys and blocks, of the frog. and even Without the use of keys alone, While any form of stop (such as a rivet thereby simplifying and materiallyimproving passed through the flange or web of a wing and cheapening the construction. rail behind a clamp) may be used to prevent 30 To prevent any possibility on the part of slipping of the clamps from the positions to the clamps, when once set by driving them to which they are adjusted by driving, I prefer their respective positions, of slipping back, I a stop that may be adjusted to follow the diprovide suitable stops, and it stops are emrection of adjustment of the clamps in tightployed at all I prefer a particular form of ening the loosened parts of the frog, and such 3 5 stop, hereinafter described, as affording esan adjustable stop is shown in Fig. 2, and as pecial advantages.

Wha't I claim as new, and desire to secure by Letters Patent, is-

1. A railway-frog having its parts secured together by clamps D and D ,embracing the frog across its base, with their hook ends bear' ing directly andsolelyagainstthe outer sides of the wing-rails, whereby the wedge shape of the frog alone serves for wedging the clamps in their operative" positions,- substan tiallyras described.

2; A railway-frog having its parts secured together by clamps D and D, embracing the frog across its base,wit-h their hook ends bearing directly and solely against the outer sides of the wing-rails, whereby the wedge shape of the frog alone serves for wedging the clamps in their operative positions, and stops provided on the frog against the rear sides of the clamps, substantially as and for the purpose set forth.

3. A railway-frog having its parts secured together by clamps D and D", embracing the frog across its base, with their book ends bearing directly and solely against the outer sides of the wing-rails, whereby the wedge shape of the frog alone serves for wedging the clamps in their operative positions, and stops adjustably secured to the wing-rails against the clamps, substantially as and for the purpose set forth.
